Mesh Process Node
Overview
The Mesh Process Node processes an input polygon mesh and generates a point cloud that can be used for finding model features.

Data Source

- Model Mesh
A polygon mesh for the model (.ply). Usually from Reader.
Process Settings

- Process Type (Default: Generate Cloud)
- The type of mesh processing performed. Select from one of “Generate Cloud” or “Generate Edge”.
Generate Cloud: Generates a dense cloud of the mesh’s surface.
Generate Edge: Generates a point cloud with the mesh’s edges. Recommended for flat objects.
Procedure to Use
- Insert a Reader, and a Mesh Process node.
- In the Reader node, read a mesh file. Here is a mesh file if you need one.
- In the Mesh Process node, link to the Reader’s outputMesh.
- You can visualize the output by checking the checkboxes beside the display window.
- Select Generate Edge and run the node.
- Select Generate Cloud and run the node.
Exercise
You are given this mesh object, which looks like this:

What Process Type is better for this particular object?
Answers for Exercise
Since the object is very flat, the “Generate Edge” process type is the better option.
